| /**
 | |
|  * This method is like `_.difference` except that it accepts `iteratee` which
 | |
|  * is invoked for each element of `array` and `values` to generate the criterion
 | |
|  * by which they're compared. The order and references of result values are
 | |
|  * determined by the first array. The iteratee is invoked with one argument:
 | |
|  * (value).
 | |
|  *
 | |
|  * **Note:** Unlike `_.pullAllBy`, this method returns a new array.
 | |
|  *
 | |
|  * @static
 | |
|  * @memberOf _
 | |
|  * @since 4.0.0
 | |
|  * @category Array
 | |
|  * @param {Array} array The array to inspect.
 | |
|  * @param {...Array} [values] The values to exclude.
 | |
|  * @param {Function} [iteratee=_.identity] The iteratee invoked per element.
 | |
|  * @returns {Array} Returns the new array of filtered values.
 | |
|  * @example
 | |
|  *
 | |
|  * _.differenceBy([2.1, 1.2], [2.3, 3.4], Math.floor);
 | |
|  * // => [1.2]
 | |
|  *
 | |
|  * // The `_.property` iteratee shorthand.
 | |
|  * _.differenceBy([{ 'x': 2 }, { 'x': 1 }], [{ 'x': 1 }], 'x');
 | |
|  * // => [{ 'x': 2 }]
